Amadeus is located near the bathurst and clark intersection in the plaza next to the Petro-Canada. I came here with a couple friends on a sunday afternoon and it was fairly crowded at that time but was staffed well enough to make everything flow without too much of a wait time.
When I was looking at the cakes a staff member offered to help which narrowed my choices down from the good selection of cakes that they had on display. I got a Lotus mini cake ($6.50) which was really light and delicious. The only downside to this place is the price, but the quality definitely seems to be there. Their bigger cakes are more expensive ($30+) but they all looked very delicious. I'll be back to try more of what they have to offer.
